Example sentences for: chromatid
How can you use “chromatid” in a sentence? Here are some example sentences to help you improve your vocabulary:
First, we assume the previous model for alternative processing, that the CR boundaries are not efficiently broken on each chromatid, sometimes leaving the common region linked to a left or right arm [ 27 ] . We assume three trans -acting components and three kinds of cis -acting sites.
PCS of homologous chromosomes and sister chromatids prior to establishing proper kinetochore-spindle attachment during meiosis I increases the probabilities of both homologues going to the same pole and of equational division of sister chromatids during anaphase I. Upon normal fertilization, MII oocytes with an additional chromosome result in trisomic zygotes; whereas oocytes containing an extra chromatid would be expected to produce 50% trisomic zygotes due to random segregation during anaphase II.
The first model is what we take to be the accepted model in the field for chromatid breakage and telomere formation at a single TAS, and what we propose also to be the mechanism operating at the arm-distal single-TAS regions.
Separase is needed for inactivating cohesions and enabling sister chromatid separation [ 35 36 37 ] in both fission yeast [ 38 ] and mammalian cells [ 39 ] . Although differences have been reported among species [ 40 ] and cell types [ 41 ] , it appears that the majority of cohesion is removed from mammalian chromosomes during prophase and prometaphase; whereas, a lesser amount remains at kinetochores until anaphase onset.
These properties correlate with the previously-inferred incompleteness of chromatid cutting that occurs in each of these regions.
